and for those who think they are outsmarting the pole, the pole said one or the other, not use one to get the other :P good try though.

The OP did post this as well: "EDIT- you can still have the other thing.. one is just handed to you free of work and the other must be worked for as usual."

So if you choose the cars, you can still get women with your usual effort, though a nice car may help. If you choose the girls, you can also still work hard to get the nice cars. With the OP's edit, I would take the cars because it would be far more difficult to make the money for the cars I would want to buy, whereas I can still meet attractive girls anywhere.

Now if you could only have one and never the other, then the girls become my logical choice.
